Question
Which among the following statements is / are correct ?
Options
A.XeF4 and SbF5 combine to form salt.
B.He and Ne do not form clathrate.
C.He diffuses through rubber and polyvinyl chloride.
D.He has lowest boiling point in its group.
Solution
(A) XeF4 + SbF5 → [XeF3]+ [SbF6]-
(B) He and Ne being smaller in size did not trape in the cavities formed by the water molecules and therefore, He and Ne escape from the cavities.
(C) Correct statement.
(D) He having lower atomic weight in zero group has small van der Waal′s force of attraction ; so it has least boiling point.
(B) He and Ne being smaller in size did not trape in the cavities formed by the water molecules and therefore, He and Ne escape from the cavities.
